> As part of the coprocessor deployment, we have realized that it will be much cleaner to have the coprocessor code sit in a package which does not depend on hadoop-yarn-server classes. It only needs hbase and other util classes.
> These util classes and tag definition related classes can be refactored into their own independent "definition" class package so that making changes to coprocessor code, upgrading hbase, deploying hbase on a different hadoop version cluster etc all becomes operationally much easier and less error prone to having different library jars etc.
